Synthesis and Crystal Structure of the Copper(Ⅱ) Complex with 1,10-Phenanthroline-5,6-dione

<正>The complex Cu(phon)(NO3)2(CH3CN) (phon = 1,10-phenanthroline-5,6-dione) has been synthesized and characterized by elemental analysis, infrared and UV-Vis spectra. X-ray diffraction analysis at room temperature indicates that the complex crystallizes in orthorhombic system, space group P212121 with a = 8.353(1), b = 11.299(2), c = 17.764(2) A, V= 1676.5(4) A3, Z = 4, C14H9CuN5O8, Mr = 438.8, Dc = 1.739 g/cm3, F(000) = 884 and μ(MoKα) = 1.361 mm-1. The final R and wR factors for the observed reflections with I > 2σ(I) are 0.0353 and 0.0855, respectively. R = 0.0432 and wR = 0.0899 for all data. The structure of the title complex consists of a neutral mononuclear entity. The central Cu (II) atom is five-coordinated by two nitrogen donors of one ligand, two unidentate NO3- ions and one CH3CN molecule. The coordination geometry of Cu (II) can be considered as a distorted trigonal bipyramidal configuration. The complex ability of the NO3-ion has more effect than that of the ClO4- ion on the structure of th

Synthesis and Crystal Structure of Dinuclear Copper Complex[Cu（CH2O（C6H4）N=C（C6H4）O）（Py]2

1 INTRODUCTION Synthesis of transition metal complexes with Schiff-base has been a subject of considerable importance [1,2]. They are not only good complexing agents for Schiff-base, but also good bactericide and antitumour agent [3,4]. At present, there is a spectacular growth in this field. Recently, some bridged binuclear complexes have received much attention on account of their biological relevance and condensed-phase magnetic properties[5,6]. Especially, the complexes containin…

The compound contains two crystallographically unique monovalent copper ions, Cu(1) and Cu(2). The Cu(1) atom in the tetrahedral site, is coordinated to two bridging Cl^? and two N atoms in phen. The Cu(2) atom with a slightly distorted triangular planar geometry, is coordinated to three Cl^?.

Synthesis,Charactarization and Crystal Structures of Lanthanide Phenoxyacetate Complexes with1,10—Phenanthroline

Three new lanthanide phenoxyacetate complexes with 1,10‐phenanthroline. [Nd(POA)₃ (phen)]₂ · 2C₂H₅OH (1), [Eu(POA)₃‐ (phen)]₂ · 2C₂H₅OH (2) and [Sm(POA)₂(DMSO)(phen)]₂‐ (ClO₄)₂ (3) (POA= phenoxyacetate, phen = 1,10‐phenanthroline, DMSO = dimethyl sulfoxide), were synthesized and characterized by elemental analyses, IR, UV‐vis and FAB‐MS spectra. Their structures were determined by single crystal X‐ray diffraction analysis. In complexes 1 and 2, the carboxylate groups are bonded to Ln³⁺ ion in three modes: the chelating bidentate, the bridging bidentate and the bridging tridentate. In complex 3, the carboxylate groups are bonded to Sm³⁺ ion only involved in one mode: the bridging bidentate. The luminescence behavior of complex 2 was also studied by means of emission spectra.

Synthesis and Crystal Structure of a New Complex [CuL（Phen）].NO3

1 INTRODUCTION The functions of transition metals present in the active sites of metalloproteins range from stabilizing the protein structure, affecting the enzymatic activity to controlling the cell metabolism[1]. Copper con- tained metalloproteins are quite widespread, with copper exhibiting various coordination numbers and geometries[2, 3]. Characterization of the model copper complexes mimicking copper-proteins has led to the better understanding of the chemistry of copper in biologic…
